ios - Cannot open file created by previous app version in the user library -


oddly can't find info regarding error. i'm updating old ios app stored user files in user library, in subdirectory called "private documents".

i can list files created fine, cannot read them, , receive error "the file “1.xxx” couldn’t opened because don’t have permission view it."

let urls = filemanager.default.urls(for: .librarydirectory, in: .userdomainmask) guard let documentdirectory = urls.first else {     print("cannot find old lib documents directory")     return }  guard let files = try? filemanager.default.contentsofdirectory(at: documentdirectory.appendingpathcomponent("private documents", isdirectory: true), includingpropertiesforkeys: nil, options: filemanager.directoryenumerationoptions.skipshiddenfiles) else {     print("cannot load old lib files directory")     return }

files contains array of file urls in directory, correctly.

however, if call filemanager.default.isreadablefile, function returns true, trying copy file data(contentsof: file) object fails above error.

help appreciated!

update: checked app signing etc, comparing current app store version testflight build have same issue.

well well... issue file reading directories (packages). hence permissions, ownership, isreadable/iswritable correct.

it's shame apple error doesn't state that's issue!

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
