XCTAssertEqual macro no longer accepts CGPoint in Xcode 5.1

Originator:combinatorial
Number:rdar://16281876 Date Originated:3/10/2014
Status:Open Resolved:
Product:Developer Tools Product Version:XCode 5.1
Classification: Reproducible:Always
 
Summary:
This code worked before v5.1 of Xcode:

CGPoint p1 = CGPointMake(1,2);
CGPoint p2 = CGPointMake(2,3);
XCTAssertEqual(p1, p2, @"Points not equal");

And in Xcode gives the error:

Invalid operands to binary expression ('typeof (p1)' (aka 'struct CGPoint') and 'typeof (p2)' (aka 'struct CGPoint'))

This is because the macro has changed an is doing a != comparison on the arguments which is invalid for a struct.

Steps to Reproduce:
1. See code in description.

Expected Results:
XCTAssertEqual works for CGPoint (and other structs supported by NSValue)

Actual Results:
Compilation fails.

Version:
XCode 5.1 (5B130a)

Notes:
Workaround is to use:

XCTAssertEqualObjects([NSValue valueWithCGPoint:p1],
                      [NSValue valueWithCGPoint:p2],
                      @"Points not equal");

Configuration:
OSX Mavericks
ios 7.1

Comments

You could always use something like XCTAssertTrue(CGPointEqualToPoint(p1,p2), points not equal);

You probably shouldn't be comparing points directly with == anyway, hence the helper function.
