So my potential solution for this is:
NSSpellChecker *checker = [NSSpellChecker sharedSpellChecker];
__block NSRange range = NSMakeRange(0, 0);
while (range.location < [aString length]) {
dispatch_sync(dispatch_get_main_queue(), ^{
range = [checker checkSpellingOfString:aString startingAt:range.location];
});
// update range
}
Where this piece of code will run on multiple threads.
Does this look like a reasonable approach to ensuring thread safety?
