#import "Project-Swift.h" comes some strange issue - ios

Question

Project is mixed with oc and swift.
#import "myProjectName-Swift.h" in the AppDelegate.m,:
Project is Objective-c language created by me, and using almost swift language to write. and In the Appdelegate.m I want to use swift's class, and so
But unfortunate, my project occurs some error in myProjectName-Swift.h:
The code is below:
SWIFT_CLASS_PROPERTY(#property (nonatomic, class, readonly, copy)
NSString * _Nonnull ;)
+ (NSString * _Nonnull);
SWIFT_CLASS_PROPERTY(#property (nonatomic, class, readonly, copy)
NSString * _Nonnull ;)
+ (NSString * _Nonnull);
SWIFT_CLASS_PROPERTY(#property (nonatomic, class, readonly, strong) UIColor * _Nonnull APP_COLOR;)
+ (UIColor * _Nonnull)APP_COLOR;
The error are:
Expected ';' at end of declaration list.
cannot declare variable inside #interface or #protocal
Expected member name or ';' after declaration specifiers
Expected ']'
Property requires fields to be named
Missing '[' at start of message send expression
And so on...
Attension
And In the global swift, I set Chinese characters variable like this:
class Global: NSObject {
}
EDIT - 1
Because I think a error point out the static let "'s ，so I annotation this line, project will not show this error. Or I delete the ，`, will not show the error too.

Objective-C doesn't support Unicode in identifiers (variable names, class names, method names etc), only in string literals ("🏋"). Only a subset of ASCII is allowed (start with _[a-zA-Z], +[0-9] afterwards).
Example:
class MyClass : NSObject {
func 😞() { }
}
This will break when you compile it in a mixed project. Instead you need to give it a valid Objective-C name, like so:
class MyClass : NSObject {
#objc(unhappyFace)
func 😞() { }
}
which will compile (and you need to access it as unhappyFace on the ObjC side).
Or in your example you need to modify your Global object:
class Global: NSObject {
#objc(emptyNumberNotAllowed)
static let 手机号码不能为空 = "手机号码不能为空"
... etc ...
}
