Comment at: clang-tidy/objc/PropertyDeclarationCheck.cpp:123
+ size_t Start = PropertyName.find_first_of('_');
+ assert(Start != llvm::StringRef::npos);
+ auto Prefix = PropertyName.substr(0, Start);
----------------
Can you also check that Start + 1 < PropertyName.length() (e.g., the string
doesn't end with a _)?
I know the regular expression shouldn't match this, so an assert is probably
good. (There is logic later which tries to access Start + 1 without checking.)
================
Comment at: clang-tidy/objc/PropertyDeclarationCheck.cpp:129
+ auto RegexExp =
+ llvm::Regex(llvm::StringRef(validPropertyNameRegex(Acronyms, false)));
+ return RegexExp.match(llvm::StringRef(PropertyName.substr(Start + 1)));
----------------
Don't need to explicitly wrap in llvm::StringRef, that class has an implicit
constructor from std::string.

+@interface Foo (Bar)
+@property(assign, nonatomic) int abc_NotCamelCase;
+// CHECK-MESSAGES: :[[@LINE-1]]:34: warning: property name 'abc_NotCamelCase'
not using lowerCamelCase style or not prefixed in a category, according to the
Apple Coding Guidelines [objc-property-declaration]
+@property(assign, nonatomic) int abCD_camelCase;
+// CHECK-MESSAGES: :[[@LINE-1]]:34: warning: property name 'abCD_camelCase'
not using lowerCamelCase style or not prefixed in a category, according to the
Apple Coding Guidelines [objc-property-declaration]
+// CHECK-FIXES: @property(assign, nonatomic) int abcd_camelCase;
+@property(assign, nonatomic) int abCD_NotCamelCase;
----------------
Can we add checks for properties whose names end with _?
