Bug ID: 28058
Summary: Incorrect compiler error
Product: new-bugs
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org

Test case
Compiling the attached test code with:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
-isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk
-arch armv7 bug.m
> bug.m:10:17: warning: 'NSObject' may not respond to 'initWithCoder:'
> return [super initWithCoder:p0];
> ~~~~~ ^
> bug.m:10:17: error: 'initWithCoder:' is unavailable
> /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIActivityViewController.h:23:1:
> note: 'initWithCoder:' has been explicitly marked unavailable here
> - (nullable instancetype)initWithCoder:(NSCoder *)aDecoder NS_UNAVAILABLE;
> ^
> 1 warning and 1 error generated.>
I'm not sure if the code should actually show an error or not, but I am sure
there's nothing related to UIActivityViewController.h at all in the code
snippet (so if the code is invalid, the error message itself is still
incorrect).
