Question

I tested Xcode 7 with but my cocos2d 2.1 games crash on simulator or on devices:

I'm "rae" on forum.cocos2d-objc.org and I might as well put my answer here as well, since all roads lead to StackOverflow. :-)

If you are using an older release of Cocos 2D, this may help. I edited CCGLProgram.m to change the beginning of the -(BOOL)compileShader: method thusly:

#define EXTENSION_STRING "#extension GL_OES_standard_derivatives : enable"
static NSString * g_extensionStr = @EXTENSION_STRING;

- (BOOL)compileShader:(GLuint *)shader type:(GLenum)type byteArray:(const GLchar *)source
{
    GLint status;

    if (!source)
        return NO;

    // BEGIN workaround for Xcode 7 bug
    BOOL hasExtension = NO;
    NSString *sourceStr = [NSString stringWithUTF8String:source];
    if([sourceStr rangeOfString:g_extensionStr].location != NSNotFound) {
        hasExtension = YES;
        NSArray *strs = [sourceStr componentsSeparatedByString:g_extensionStr];
        assert(strs.count == 2);
        sourceStr = [strs componentsJoinedByString:@"\n"];
        source = (GLchar *)[sourceStr UTF8String];
    }

    const GLchar *sources[] = {
        (hasExtension ? EXTENSION_STRING "\n" : ""),
    #ifdef __CC_PLATFORM_IOS
        (type == GL_VERTEX_SHADER ? "precision highp float;\n" : "precision mediump float;\n"),
    #endif
        "uniform mat4 CC_PMatrix;\n"
        "uniform mat4 CC_MVMatrix;\n"
        "uniform mat4 CC_MVPMatrix;\n"
        "uniform vec4 CC_Time;\n"
        "uniform vec4 CC_SinTime;\n"
        "uniform vec4 CC_CosTime;\n"
        "uniform vec4 CC_Random01;\n"
        "//CC INCLUDES END\n\n",
        source,
    };
    // END workaround for Xcode 7 bug

It's a hack, but it works for up to Xcode 7 beta 2. Hope this is helpful to someone googling for this.
