• Odd UI bug in Xcode 4.3.2

  - by scordova88

  I have this annoying UI bug when using xCode 4.3.2. Every time i press the space bar, the whole text scroll view jumps. Does anyone know why this happens, or how to stop it? edit: is happens, for example, when I'm writing comments in the code and the sentence contains a space. IT can be anywhere on the document, even in the center, doesnt have to be at the bottom of the page. After it "jumps" it goes back to where it was.

• Are Subversion 1.6 & Xcode 3.2 compatible?

  - by Meltemi

  Trying to get Xcode to work with Subversion server. Server: Subversion upgraded to 1.6.9 (Mac OS X Leopard 10.5.8) Client: Xcode 3.2.1 (Snow Leopard 10.6.2 with Subversion 1.6.5 though not sure that matters) Repository on server is setup and working fine via command line. However, I get an error when trying to create the Repository connection in Xcode: Error: 160043 (Unsupported FS format) Description: Expected FS format '2'; found format '4' a Google search seems to say that the server needs to be updated...but it's running 1.6.9 which is the most current version I'm aware of. Anyone know how to make this work? Is it even possible? I'm well aware of the command line usage but I would like to get Xcode & SVN talking... Revisiting this after some time: Using command line: username$ svn+ssh://hostname/Library/Subversion/Repository/test yields the same result: Description: Expected FS format '2'; found format Can anyone verify that I need to upgrade Subversion on the client machine to match version on server (1.6.9)?!? was hoping i wouldn't have to unless it was a "major" revision (ie. 1.5.x - 1.6.x)

• Sometimes Xcode appears to ignore target build settings?

  - by Derek Clarkson

  Hi all, I've created a iPhone static library project with two targets like this Project -- Library (Device) target -- Library (simulator) target The device target has the SDK set to the device so it produces an armv6/7 library and the simulator target is set to the simulator SDK so it produces an i386 library. The issue I'm having is that the SDK settings on the targets keep getting overridden by the XCode active target setting. i.e. if I build the device target, but the XCode window is showing the active SDK as being the simlulator, XCode will build a simulator library instead of a device library, ignoring the settings of the target. Although it will put it into the *-iphoneos/ directory in the build directories! I originally had the same issue with another static library project, and after a lot of playing around got everything to work correctly. i.e. The targets ignore the XCode active SDK because they have their own specifications of what to build. The problem is that I don't know what made it work in that project and I have not been able to reproduce the issue in it either. Does anyone have any ideas as to what is going on? ciao Derek

• Xcode "Build and Archive" from command line

  - by Dan Fabulich

  Xcode 3.2 provides an awesome new feature under the Build menu, "Build and Archive" which generates an .ipa file suitable for Ad Hoc distribution. You can also open the Organizer, go to "Archived Applications," and "Submit Application to iTunesConnect." Is there a way to use "Build and Archive" from the command line (as part of a build script)? I'd assume that xcodebuild would be involved somehow, but the man page doesn't seem to say anything about this. UPDATE Michael Grinich requested clarification; here's what exactly you can't do with command-line builds, features you can ONLY do with Xcode's Organizer after you "Build and Archive." You can click "Share Application..." to share your IPA with beta testers. As Guillaume points out below, due to some Xcode magic, this IPA file does not require a separately distributed .mobileprovision file that beta testers need to install; that's magical. No command-line script can do it. For example, Arrix's script (submitted May 1) does not meet that requirement. More importantly, after you've beta tested a build, you can click "Submit Application to iTunes Connect" to submit that EXACT same build to Apple, the very binary you tested, without rebuilding it. That's impossible from the command line, because signing the app is part of the build process; you can sign bits for Ad Hoc beta testing OR you can sign them for submission to the App Store, but not both. No IPA built on the command-line can be beta tested on phones and then submitted directly to Apple. I'd love for someone to come along and prove me wrong: both of these features work great in the Xcode GUI and cannot be replicated from the command line.

• Upgraded to Xcode 4 -- Endless stream of duplicate symbol errors causing build errors

  - by D-Nice

  Everything was working perfectly fine in Xcode 3 yesterday before I upgraded. So I completed the upgrade, restarted my computer, and opened my old project. I had to reconfigure a few settings like the header paths so that I could begin to compile. I'm using AdWhirl for ad mediation, and at this point my errors begin to read something like duplicate symbol _OBJC_METACLASS_$_SBJSON in /Users/Admin/Desktop/TMapLiteAdwhirl/AdWhirl/MMSDK/libMMSDK.a(SBJSON.o) and /Users/Admin/Library/Developer/Xcode/DerivedData/TruxMapLite-bgpylibztethnlhkfkdumpvrjvgy/Build/Intermediates/TruxMapLite.build/Debug-iphoneos/TruxMapLite.build/Objects-normal/armv6/SBJSON.o for architecture armv6 The library it's referring to is the SDK for one of the ad networks I'm including in AdWhirl. Both of the 'duplicate symbols' refer to the SAME FILE, but they use different paths. If I had still had XCode 3, I would simply try excluding these libraries from the build path, but I have no idea how that can be done in Xcode 4. I've tried everything all the way down to deleting the library and all associated files from my project, but when I do this, i will simply get the same type of error for a different library in the AdWhirl directory. This is incredibly frustrating because before my upgrade everything was working smoothly and I was prepared to submit my binary. If anyone has any advice, id be more than happy to give it a try. Thanks!

• Xcode Code Sense horribly broken?

  - by Philippe Leybaert

  Ever since I started using Xcode, I've experienced extremely annoying problems using Xcode and Code Sense. The problem is that when Code Sense kicks in for code completion, sometimes the source code text below the line I'm working on goes "crazy". If I continue typing, the problem gets worse, and after a while the source code is completely screwed up (funny colors, missing lines and characters, ...). Strange enough, the source code itself is unaffected, because when I select another source file and then go back to the one I was working on, everything looks fine again. The problem can be seen in this screencast: http://www.screencast.com/t/OGY3NWE5 Interesting facts: This problem has occurred on 3 different machines, so it's not related to a corrupt installation. Sometimes it's fine for a while (up to one hour) after launching Xcode, but once it starts happening, it's getting worse and worse, until Xcode is restarted. Then it's fine again (for a while) I've searched the web for similar experiences, and I can't find anything. I would think that it is a known problem, since it occurs on 3 different Macs here (both running 10.5 and 10.6). Anyone having the same problems? Or a suggestion for fixing this?

• Image does not update when file name remains the same in XCode 3.1.2

  - by vman049

  Hi Everyone, I'm using XCode version 3.1.2 and am developing for iPhone using the Simulator with iOS 2.2.1 on Leopard. I had an image file named "img.jpg" in my project which I decided to switch for a different file. After adding the new file into the XCode Resources folder, I removed the first file and renamed the new file to the same name as the previous one, "img.jpg." When I run my program, however, the Simulator loads the old image instead of the new one, even though the old one has been deleted from disk (not just the reference). I tried changing the name of the file to "img2.jpg," and it worked like it should - loading the new image, but I want to keep the name "img.jpg." I ran a search with Spotlight for "img.jpg" to see if there was another copy stored somewhere that XCode was using, but it only returned my new image file. I have tried uninstalling the app from the Simulator and running the application again, but that also does not fix the problem. What must I do for XCode to recognize that I want to use the new image file and not the old one? Thanks for your help!!

• Remote iPhone / xCode application development?

  - by ANE

  4 java developers are new to iPod Touch/iPhone app development. They have an idea for an app. They have never used Xcode or Macs before. Instead of spending money for a new iMac or Mac Mini for each of them, my boss would like to sell them a $999 Apple server, hosted at a facility connected a single T1 line, and have all 4 people work remotely in Xcode. Is this feasible? Is anyone doing anything like this? Specifically, is 1 T1 enough for realistic remote app development? Would they have to work in black & white via Logmein or Gotomeeting to get decent speed? Can four people work remotely together on an Xcode project at the same time? Do they absolutely need their own Macs to connect their iPod Touches or iPhones physically to, or can they connect to their existing PCs with iTunes and install their in-development apps that way?

• XCode 3.2.1 and Instruments: Useless Stack Trace

  - by Jason George

  I've reached the stage where it's time to start tracking down memory leaks and, to my dismay, Instruments is giving me very little to go on (other than the fact that I definitely have leaks). My stack trace contains no information other than memory addresses. Since I'm working on a new project and I've transitioned to version 3.2.1 of XCode in tandem, I'm not sure if it's my program configuration or XCode that's causing the problem. I have found one reference to the issue coupled with a post on the dyld leak that seems to be prevalent with the 3.2.1 release. Since I haven't been able to find much on the problem I'm guessing it's something I've created rather than a systematic issue with XCode. If someone has any idea where I might have thrown a wrench in the works, I would love some pointers. Also, if someone could just verify that the stack trace is indeed functioning properly in 3.2.1 that would be useful as well.

• How to start a major iPhone app update in Xcode

  - by Eric

  I have an app in the iPhone app store and have released several minor updates to it. I want to begin work on some major feature additions and reorganization, but don't want to lose the source code of my most recent version in case everything goes horribly wrong. Should I start a new Xcode project from scratch and copy my existing source in? If I do this will I be able to submit the build from this new project as an update or will Apple complain that the build comes from a different Xcode project? I've seen (but not used) Xcode's "Snapshots" and "Source Control" features - are these what I'm looking for? Any help or direction greatly appreciated.

• Add a custom compiler to XCode 3.2

  - by racha

  I have a working gcc 4.3.3 toolchain for an ARM Cortex-m3 and would like to integrate it into XCode. Is there a way to set up XCode (3.2) to use this gcc toolchain instead of the built-in GCC 4.2? What I've tried so far: I've added a modified copy of the GCC 4.2.xcplugin and changed the name, version and executable path. It shows up in XCode but whenever I set the "C/C++ Compiler Version" to the custom compiler it fails with Invalid value '4.3.3' for GCC_VERSION It seems like the valid version numbers are hardcoded somewhere else because even when I remove the original GCC 4.2.xcplugin, the value 4.2 remains valid (but is not visible in the "C/C++ Compiler Version" drop down anymore).

• XCode 3.2 - can't create Objective-C class

  - by Urizen

  My installation of XCode 3.2 has begun to exhibit some strange behaviour. When I try to add a basic Objective-C classs (inheriting from NSObject), in my iPhone project, I get the following popup: "Alert. Couldn't load the next page". The above-mentioned error happens at the point of trying to create the file (i.e. the creation process doesn't get to the stage where you are asked to input the file name). It might also be worth mentioning that where there previously used to be a description for the file (in the file creation window) it now states "No description available". I can create other files (e.g. UIViewController subclass etc.) but not the basic Objective-C class. I have updated the documentation and restarted the machine and xcode several times without success. I would be extremely grateful for any assistance as I am relatively new to the XCode environment.

• XCode Developer Documentation crashes after clicking any link on the startup screen

  - by Noah Sussman

  I just installed XCode 3.2.1. When I open the Developer Documentation and click any link on the startup screen, XCode crashes. Has anyone run into this problem? Also hints as to how to debug would be excellent -- I've only been using XCode for a week. I can still get into the documentation if I open some code and then right-click a symbol and choose "Find in Documentation." But its annoying that I can't just open the docs and browse them.

• Launching desired version of XCode from Finder

  - by Andy J Buchanan

  My google-fu has failed me, and I guess this may be basic OS X/Xcode knowledge but.... When I double click .xcodeproj files, I'm getting the Beta I have installed launching instead of the stable release - which is the one I actually want. I have tried changing the launch program in the finder info window, but it always displays as "Xcode" and doesn't seem to accept that there are different versions - even though it offers them to me in the drop down list. Is there an xcode setting for this? Thanks.

• xCode screensaver with openGL

  - by moka

  Hi, I am currently simply trying to build a simple screen saver in xcode 3.2 on osx 10.6.3 using an openGL view as described in this article: http://cocoadevcentral.com/articles/000089.php anyways even if I use the exact same code from the example all I see when testing the screen saver is a black screen. I looked in OSX Console if it tells me anything useful. the only thing I get is something like this: [0x0-0x1e01e].com.apple.systempreferences[629] System Preferences(629,0x7fff71071be0) malloc: reference count underflow for 0x20057be80, break on auto_refcount_underflow_error to debug. System Preferences[629] invalid context I have no idea what is wrong, so I would be glad if someone could tell me how to use openGL together with the screensaver template in xCode 3.2. Also, is there a way to make another target so I can preview the screensaver from within xCode? Thanks!

• xCode complitions, spelling checkings stoped

  - by SentineL

  My xCode 4.3.2 stopped to show up spelling errors and completions for code. The only way to find out if there is any error in the code - build it. xCode colores only keywords such as if, else, for etc. All other code hasn't colored. Shown only a few very strange completions. For example: CGPoint p; p.y // complition is "YES" p.x // complition is "xor" Completions for methods calls are only nearaly used methods. How can I fix this? I rebooted my mac several times allready, and didn't find any staff obout this in xCode's preferences.

• NoClassDefFoundError when running java tool under Xcode

  - by pancake

  Hi all, I'm trying to create a Java Tool by using Xcode. I've already changed my build.xml to have Xcode target java 1.6 and not 1.3 so I can use generics. I'm getting no build errors and using 'javac' and 'java' in the terminal works. Now I want it to work in Xcode as well. I keep getting the following error: Exception in thread "main" java.lang.NoClassDefFoundError: MyClass where 'MyClass' is the class containing the main method. It probably has something to do with the classpath, which as the build.xml prescribes is "${bin}". There is a bin folder in my project folder, and it contains all the .class files needed to run the program. If anybody could help me, it'd be great!

• XCode 5 says I got a duplicate, which I don't

  - by GoodMove

  The point is every time I try to run a C++ code in XCode 5 (the file s "File.cpp") xcode returns this: duplicate symbol _main ld: 1 duplicate symbol for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation) And it only returns the error, when I got the following function whatever it contains: int main() { } I checked the folder, which XCode points to (where it says the duplicates are placed), but didn't find anything though. What am I supposed to do??? #include "File.h" using namespace std; void func (void){ cout << "Hello World!" << endl; }

• Taming XCode’s auto-complete options

  - by Nippysaurus

  I am fairly new to XCode and the Objective-C language. When I am instantiating a class, for example an NSMutableArray, XCode will provide a whole lot of auto-complete options. Even for an empty class which simply extends an NSObject has many options, most of which seem completely useless. What is the reason for having so many auto-complete options, or can they be "tamed" in the preferences?
