Thanks Steve, I too suggested a recursive function solution but my team favored the threading/semaphore route.

Thanks for all your help. I got it working. In case anyone needs sample code, here is how I handle uploading a file by appending 5MB chunks.... let chunkLength:UInt64 = 1024 * 1024 * 5 //in MB let fileLength:UInt64 = UInt64(data.length)//Double(data.length)/1024/1024 //in MB print("FILE LENGTH: \(fileLength)") print("CHUNK…

ok, so now i'm playing around with waiting for each append to return before the next one is called and I'm getting successful (void) returns.

Here's my latest code. It seems like the append operations aren't being processed in the order they are called, so I'll get incorrect offset errors. For example, I had seven append calls, two succeeded, five failed. let chunkLength:UInt64 = 1024 * 1024 * 5 //in MB let fileLength:UInt64 =…

Can I only call another append when the previous append has returned? Currently, I'm calling all of them in a while loop and not waiting on a return.

Before I share my latest code, let me make sure I understand the offset. It says... <EM>offset</EM> The amount of data that has been uploaded so far. We use this to make sure upload data isn’t lost or duplicated in the event of a network error. Does this mean the amount of data uploaded in previous call(s)? (i.e., does not…

I'm getting successful append results...but the uploadSessionFinish keeps throwing an HTTPError. Do I need to do any memory management with how many appends I can do during a session? client.files.uploadSessionAppend(sessionId: result.sessionId, offset: startPosition, body: tempData).response { reponse, error in if let…

Thanks, so now i'm chunking up my file and upload is successful for files 200MB or less but now I get a memory warnings for anything bigger. Am I suppose to send the first chunk with sessionStart, and the last chunk with sessionFinish? Or should the start and finish have empty body data and append all the chunks through…

Thanks for working with me on this, but my HTTPError comes back as... HTTPError[nil]: nil: Optional(") Here's my code.... //trying to upload a 33MB file in 5MB chunks let data:NSData = NSFileManager.defaultManager().contentsAtPath(path)! let chunkLength:UInt64 = 1024 * 1024 * 5 //in MB let fileLength:UInt64 =…

cool, thanks, i'll give it a shot. I was getting an HTTP error.

thanks, so no cancel for downloads or uploads?

Thanks, I'm gonna try a bigger video. A friend suggested that it might be fully downloading that fast and what I'm seeing in the console is queued data.

i decided to call a completionHandler after printing the NSData to console. That seems to introduce the delay of fully downloading the file before the completionHandler is called. 

I'm actually getting the response back immediately, then the data from the video comes streaming across. There's no delay. In other words, it's giving me a response back when the file isn't fully downloaded. I'm not actually trying to play the video just yet. I'm trying to notify the user when it's fully downloaded, but…

Thanks but when I execute these print statements inside the block, it takes about 3-5 seconds to print the NSData to the console, so I can't play the video back until it finishes. print("*** Download file ***") let data = NSData(contentsOfURL: url) print("Downloaded file data: \(data)")
