Issues playing local files with AVPlayer?

Basically, I'm writing a video file to the Application Support directory and then saving it's path:

NSString *guid = [[NSUUID new] UUIDString];
NSString *outputFile = [NSString stringWithFormat:@"video_%@.mp4", guid];
NSString *outputDirectory = [NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *tempPath = [outputDirectory stringByAppendingPathComponent:outputFile];
NSURL *fileURL = [NSURL fileURLWithPath:tempPath]
// code to write a video to fileURL

I save the string path itself by calling [fileURL path];

Now later when I try to create an AVAssetItem from it, I can't actually get it to play.

EDIT:

Ok, so it seems the issue is the space in Application Support. I tried saving the file to just the Library directory and it worked fine.

So the question becomes, how can I play a video I save in the Application Support directory. I wasn't able to create a valid NSURL without escaping the space (when I tried it would return a nil NSURL) but it seems that the space/escaping doesn't allow it to play correctly.

Assume the NSURL to NSString conversion is required (unless it really should be avoided).

Also, side note, but if anyone could give some insight as to why this question was down voted so I can improve the quality of my questions, that would be appreciated. I don't understand?

While I am not informed enough to opine about whether this would change if I had used matt's recommended methods: URLForDirectory:inDomain:appropriateForURL:create:error: and URLByAppendingPathComponent: the actual issue here isn't converting an NSURL to NSString

It's that I'm saving the full URL ([fileURL path]). This is because the [NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES) objectAtIndex:0]; dynamically changes and the full path won't always point me to the appropriate file.

Instead I need to save just the name of my file (in my case I needed to persist outputFile) and then later dynamically build the the full path when I need it.

The same exact process: 

NSString *outputDirectory = [NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *tempPath = [outputDirectory stringByAppendingPathComponent:outputFile];
NSURL *fileURL = [NSURL fileURLWithPath:tempPath];

worked just fine.

TLDR: Saving a full path doesn't work
