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_VERS         


        

Answer 1

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/

As of Xcode 5.0 it is not possible to get warnings from new API calls by redefining macros.

Redefining a macro does show up in autocompletion and preprocessed preview (Assistant Editor > Preprocess) but does not trigger a warning despite using deprecate or unavailable keywords.

Xcode 5.0.1+ does show a warning so both __AVAILABILITY_INTERNAL__IPHONE_X_X and NS_AVAILABLE_IOS can now be redefined as mentioned in the question and @borrrden answer.

Code available as a Gist and as a library:

#define __IPHONE_OS_VERSION_SOFT_MAX_REQUIRED __IPHONE_5_0

#ifndef __IPHONE_OS_VERSION_SOFT_MAX_REQUIRED
    #define __IPHONE_OS_VERSION_SOFT_MAX_REQUIRED __IPHONE_OS_VERSION_MIN_REQUIRED
#endif

#if __IPHONE_OS_VERSION_SOFT_MAX_REQUIRED < __IPHONE_OS_VERSION_MIN_REQUIRED
    #error You cannot ask for a soft max version which is less than the deployment target
#endif

#define __NBU_AVAILABILITY_STARTING(version) __attribute__((deprecated("Only available in iOS " version "+"))) __attribute__((weak_import))

#if __IPHONE_OS_VERSION_SOFT_MAX_REQUIRED < __IPHONE_2_0
    #undef  __AVAILABILITY_INTERNAL__IPHONE_2_0
    #define __AVAILABILITY_INTERNAL__IPHONE_2_0 __NBU_AVAILABILITY_STARTING("2.0")
    #define __NBU_APICHECK_2_0(_ios)            __NBU_AVAILABILITY_STARTING("2.0")
#else
    #define __NBU_APICHECK_2_0(_ios)            CF_AVAILABLE_IOS(_ios)
#endif

#if __IPHONE_OS_VERSION_SOFT_MAX_REQUIRED < __IPHONE_2_1
    #undef  __AVAILABILITY_INTERNAL__IPHONE_2_1
    #define __AVAILABILITY_INTERNAL__IPHONE_2_1 __NBU_AVAILABILITY_STARTING("2.1")
    #define __NBU_APICHECK_2_1(_ios)            __NBU_AVAILABILITY_STARTING("2.1")
#else
    #define __NBU_APICHECK_2_1(_ios)            CF_AVAILABLE_IOS(_ios)
#endif

//...

#if __IPHONE_OS_VERSION_SOFT_MAX_REQUIRED < __IPHONE_7_0
    #undef  __AVAILABILITY_INTERNAL__IPHONE_7_0
    #define __AVAILABILITY_INTERNAL__IPHONE_7_0 __NBU_AVAILABILITY_STARTING("7.0")
    #define __NBU_APICHECK_7_0(_ios)            __NBU_AVAILABILITY_STARTING("7.0")
#else
    #define __NBU_APICHECK_7_0(_ios)            CF_AVAILABLE_IOS(_ios)
#endif

#undef  NS_AVAILABLE_IOS
#define NS_AVAILABLE_IOS(_ios)                  __NBU_APICHECK_##_ios( _ios )

#undef  __OSX_AVAILABLE_BUT_DEPRECATED
#define __OSX_AVAILABLE_BUT_DEPRECATED(_osx, _osxDep, _ios, _iosDep)            __AVAILABILITY_INTERNAL##_ios

#undef  __OSX_AVAILABLE_BUT_DEPRECATED_MSG
#define __OSX_AVAILABLE_BUT_DEPRECATED_MSG(_osx, _osxDep, _ios, _iosDep, _msg)  __AVAILABILITY_INTERNAL##_ios

In Xcode 5, you should be able to use/adapt the code from my answer to https://stackoverflow.com/a/19567669/473067. It could be incompatible with the use of modules, though, I haven't checked.

I posted a summary here: http://iphone.m20.nl/wp/2013/10/xcode-5-and-flagging-weak-linked-unavailable-symbols-from-a-newer-sdk/

Answer 4

Use the method described here: https://stackoverflow.com/a/8919108/480467

In addition, to get this to work under XCode 5 you need to also redefine the NS_AVAILABLE and NS_DEPRECATED macros because CFAvailability.h distinguishes between compilers that support the attribute_availability_with_message feature.
