It's work fine on iOS 11.2 but it's getting error on iOS 12 and 13.

My download function: download_image(){ this.photoLibrary.requestAuthorization().then(() => { var url="http://www.google.com/images"+this.fname+"/PROCESSED_JPEG/"+this.imgid+".jpg"; var album = 'Images'; this.photoLibrary.saveImage(url , album).then((entry=>{ this.presentToast(this.translate.instant('image Download success')); }),(error) => { // handle error this.presentToast(this.translate.instant('Download Failed')); }); }); }
