ios - NSFileManager Failing on create file -

here functions save image.

static func getdirectorypath() -> string {     let path = (nssearchpathfordirectoriesindomains(.picturesdirectory, .userdomainmask, true))[0]     return path }  static func savephoto(with path: string, image: uiimage) {     let fm = filemanager.default     let path = getdirectorypath() + path     let data = uiimagejpegrepresentation(image, 0.5)     let success = fm.createfile(atpath: path, contents: data, attributes: nil)     print("file creation \(success)") } 

and i'm calling this

      let path = "/spotcheck_\(spot.name)_photo\(indx).jpg"       photomanager.savephoto(with: path, image: photo) 

when call create file returns false every time , photo not saved.

edit: problem second line needed documentdirectory instead of picturesdirectory. shown below:

    let path = (nssearchpathfordirectoriesindomains(.documentdirectory, .userdomainmask, true))[0] 

ios apps run in sandbox. can't write pictures folder.

if want add picture user's photo library use phphotolibrary or uiimagewritetosavedphotosalbum.

if want save image within own app store file in documents folder.

fyi - when using nssearchpathfordirectoriesindomains in ios, useful directories are:

• librarydirectory
• documentdirectory
• cachesdirectory
• applicationsupportdirectory

all others useful in macos.
