Building for 64-bit architecture cause warnings about precision loss and format arguments

[gogopair]

Change project architecture to include 64-bit and build, see warning:

Implicit conversion loses integer precision: 'long' to 'int'
Implicit conversion loses integer precision: 'NSUInteger' (aka 'unsigned long') to 'int'
Implicit conversion loses integer precision: 'NSInteger' (aka 'long') to 'int'
Implicit conversion loses integer precision: 'NSInteger' (aka 'long') to 'int'
Implicit conversion loses integer precision: 'NSUInteger' (aka 'unsigned long') to 'int'
Implicit conversion loses integer precision: 'NSUInteger' (aka 'unsigned long') to 'int'
Implicit conversion loses integer precision: 'NSInteger' (aka 'long') to 'int'
Values of type 'NSUInteger' should not be used as format arguments; add an explicit cast to 'unsigned long' instead
Values of type 'NSUInteger' should not be used as format arguments; add an explicit cast to 'unsigned long' instead
Values of type 'NSUInteger' should not be used as format arguments; add an explicit cast to 'unsigned long' instead
Values of type 'NSInteger' should not be used as format arguments; add an explicit cast to 'long' instead
