Our application need to scan all media files inside iPhone and we success to do this. Then, we need to copy these files to our physical device to help our end-user to backup their file. However, as we don't have any permission on these files, we need to copy one by one file to an temporary directory inside our application, then using data streaming from this file to our physical device. This only solution cause us an limitation in our application is the free storage in the phone. If we want to copy a video of 1GB, we need to have a free storage 1GB in our iPhone in order to copy the video into temporary directory. So, that means we cannot support our user to copy many big files at the same time when the free storage of the phone is limited. Could you please help us to check if there is any way for us to have the permission on your media files, or an solution for us to stream data directly from your files to our device? And could you please kindly guide us how to have this permission (by contract, use

As our user normally have a lot of files inside the phone, so we need to support to copy in background in order to help our user backup full his data.For now, we can success to do it with NSURLSession solution via HTTP.However, by this protocol, the our copy performance is very slow (we need about 1 hours for a file of 300MB). Therefore, it's very important for us to know if you could provide us any special library that can help us to copy in background via ftp or smb protocol.In that case, could you please guide us how we can use that special library with your authorization?

I am currently working on a big project, that includes over 100 IBOutlets and a lot of code. It is impossible to still work on that project the way my Xcode is now. If i try to create an array with over 30 items, it won't stop indexing. And it takes forever to navigate or just to move an UILabel. It also complains that source editor functionality is limited. + my mac gets really hot and makes noises. I have got a MacBook Pro 13.3 Retina MF839. I have deleted derived data, and almost all other projects files.How do i fix this? Surely my mac should be able to cope with such a project(?)I put all my code in the viewController, does that play a factor?

I'm working in a project with a pretty big storyboard. Everytime the project is loaded i'm presented with 34 warnings to update frames in the Storyboard. I do it, then when I reopen the project again those settings are not saved. If I update them on my Macbook Pro (May 2015) updating frames works fine. If I am connected to my Thunderbolt Display, updating frames freezes Xcode indefinetly. Fun stuff. Anyone else have these issues?

I am writing an app and using CloudKit. The app stores its data in the public database. I’ve created a local cache so that my app can function even if the network isn’t available. I’m using CKSubscriptions and the resulting push notifications to keep changes from the cloud in sync. All of this is working well.Now, if a user has multiple devices and is running my app on all those devices, then it seems that I can no longer mark notifications as “read” (using CKMarkNotificationsReadOperation) since I won’t know when all the devices have processed them. This is particularly true if one of the devices is offline when a change happens. If I do mark the notifications as read, then when the other devices check for new notifications (using CKFetchNotificationChangesOperation) they will not see them and their local cache will be out of date.My current solution is to just leave all notifications in an “unread” state and rely on the CKServerChangeToken in CKFetchNotificationChangesOperation so that each device only grab
