ios - Get Xcode 5 to warn about new API calls

Question

There was a method for Xcode 4.x:

#define __AVAILABILITY_TOO_NEW __attribute__((deprecated("TOO NEW!"))) __attribute__((weak_import))

#if __IPHONE_OS_VERSION_MIN_REQUIRED < __IPHONE_6_0
#undef __AVAILABILITY_INTERNAL__IPHONE_6_0
#define __AVAILABILITY_INTERNAL__IPHONE_6_0 __AVAILABILITY_TOO_NEW
#endif

But that doesn't work anymore because the iOS 7 SDK Availability macros have changed and now have more variances and options:

iOS 6 SDK's AvailabilityInternal.h:

#define __AVAILABILITY_INTERNAL__IPHONE_6_0                    __attribute__((availability(ios,introduced=6.0)))
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_0    __attribute__((availability(ios,introduced=6.0,deprecated=6.0)))
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_1    __attribute__((availability(ios,introduced=6.0,deprecated=6.1)))
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_NA     __attribute__((availability(ios,introduced=6.0)))

iOS 7 SDK:

#define __AVAILABILITY_INTERNAL__IPHONE_6_0                    __attribute__((availability(ios,introduced=6.0)))
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_0    __attribute__((availability(ios,introduced=6.0,deprecated=6.0)))
#if __has_feature(attribute_availability_with_message)
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_0_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=6.0,message=_msg)))
#else
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_0_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=6.0)))
#endif
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_1    __attribute__((availability(ios,introduced=6.0,deprecated=6.1)))
#if __has_feature(attribute_availability_with_message)
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_1_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=6.1,message=_msg)))
#else
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_6_1_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=6.1)))
#endif
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_7_0    __attribute__((availability(ios,introduced=6.0,deprecated=7.0)))
#if __has_feature(attribute_availability_with_message)
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_7_0_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=7.0,message=_msg)))
#else
     #define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_7_0_MSG(_msg)    __attribute__((availability(ios,introduced=6.0,deprecated=7.0)))
#endif
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_NA               __attribute__((availability(ios,introduced=6.0)))
#define __AVAILABILITY_INTERNAL__IPHONE_6_0_DEP__IPHONE_NA_MSG(_msg)     __attribute__((availability(ios,introduced=6.0)))

Could it be that Xcode 5 has the attribute_availability_with_message feature so the old macro redefinition is no longer used?

Also it would be cool to print more than the "TOO NEW!" message with all the new introduced/deprecated information.

Edit:

Most definitions in iOS 7 SDK moved from __OSX_AVAILABLE_STARTING(_ios)/__AVAILABILITY_INTERNAL##_ios to NS_AVAILABLE_IOS(_ios)/CF_AVAILABLE_IOS(_ios), so redefining:

#undef NS_AVAILABLE_IOS
#define NS_AVAILABLE_IOS(_ios) __attribute__((availability(ios,__NSi_##_ios))) __attribute__((deprecated("TOO NEW!")))

Should work. And actually it does because Xcode 5 autocompletion shows the methods as deprecated.

Building however doesn't trigger any warning despite having the GCC_WARN_ABOUT_DEPRECATED_FUNCTIONS build option on...

I found some other information on the topic. This will redefine a different macro (NS_AVAILABLE_IOS). Perhaps it will work a bit better than

(Source https://www.albertopasca.it/whiletrue/xcode-warn-about-new-api-classes-and-methods/)

#import <availability.h>
#import <foundation/NSObjCRuntime.h>

#if( 1 )

#define APICHECK_2_0( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_2_1( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_2_2( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_3_0( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_3_1( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_3_2( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_4_0( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_4_1( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_4_2( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_4_3( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_5_0( _ios ) __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)
#define APICHECK_5_1( _ios ) __attribute__((deprecated("UNAVAILABLE PRIOR TO 5.1")))
#define APICHECK_6_0( _ios ) __attribute__((deprecated("UNAVAILABLE PRIOR TO 6.0")))
#define APICHECK_6_1( _ios ) __attribute__((deprecated("UNAVAILABLE PRIOR TO 6.1")))
#define APICHECK_NA( _ios )  __OSX_AVAILABLE_STARTING(__MAC_NA, __IPHONE_##_ios)

#undef NS_AVAILABLE_IOS
#define NS_AVAILABLE_IOS(_ios) APICHECK_ ## _ios( _ios )

#undef NS_AVAILABLE
#define NS_AVAILABLE(_mac, _ios) APICHECK_ ## _ios( _ios )

#endif

You can use conditionals the same way as before (#if __IPHONE_OS_VERSION_MIN_REQUIRED < __IPHONE_6_0 etc). Note that I have not tested this because I don't have Xcode 5 on my machine yet. If you want to turn the warnings into errors you can use __attribute__((unavailable("UNAVAILABLE PRIOR TO 6.1"))) etc.

You can also try using this program, though it is paid. http://www.deploymateapp.com/
