I am having an issue with NSURLSessionDataTask , while trying to upload a JSON object , I am getting the following message in console .
[] __tcp_connection_write_eof_block_invoke Write close callback received
[error: [89] Operation canceled]
How to solve this issue ?
May be it is related to OS_ACTIVITY_MODE settings for Schemes.
disable OS_ACTIVITY_MODE mode by following steps and check:
--- Go in Product ---> Scheme ---> Edit Scheme
--- in Run Section on the left, select Argument Tab and in Environment Variable Change value as below:
Name: OS_ACTIVITY_MODE
Value: disable
