I am trying to add annotations to my MapKit
, however the array I append to is returning nil. I used this method before to populate CollectionView

works asynchronously, you have to add a completion handler
For convenience reasons I merged fetchCity
, performRequest
and parseJSON()
into one method.
QUESTION
Good afternoon. I am working on my final year project, in my project I am using Google Maps API
to show results in CollectionView

QUESTION
I have this function where I convert a users pickup and delivery adress to coordinates. After I convert the adresses to coordinates, I want to calculate the distance for them. I convert and calculate these by using REST apis.
These are the functions where I get the coordinates
...ANSWER
Answered 2021-Mar-30 at 23:14Your third function depends on data from the first two, but the first two are independent.
You can use a DispatchGroup
to execute the third function once the first two are complete. It doesn't matter in which order the first two functions complete.
You do need to consider that one or more of the network operations may fail.
Since these network operations are asynchronous, you will need to pass a completion handler to fetchDistance
and invoke it when the work is done.
Something like
QUESTION
I have created a UITableview and added a few cells displaying the names of a couple of stocks(Apple, Tesla). I also added a right-detail text label to my cells in which I want to display the current stock price of the stocks. So far, using Finnhub.io, I was able to create an API call and store the current price data in a variable called decodedData. I was also able to print out that data in my debug console. The only problem that I'm currently facing is not showing the debug console's data in the UI cells. If anyone has any ideas on how to solve this issue, please let me know.
Here is my code for making the API call and getting the URL:
...ANSWER
Answered 2021-Mar-26 at 20:39You are actually doing it the wrong way, api calls take time and after you get the response from api, you then have to update the UI based on the results.
Problem: The problem with your code is that, at the time when cell is displayed, only the api call is made and even before getting the results your code will display the cell with empty / default data.
Solution:
(1) Make a function getStocks() in which you will call api for all the required stocks
var stockResponses = StockResponse
QUESTION
So, the issue is - I am trying to display the Mars weather from the Mars Insight API. Here is a link Insight Weather, the data is returning in JSON format and has three levels. The keys have names that change depending on the current date (sols). How to make the structure of mutable properties?... when the property names change every day. Do we have any instruments to parse such JSON?
...ANSWER
Answered 2021-Mar-24 at 08:33You cannot decode [String:WeatherData].self
because the dictionary contains other values which are not WeatherData
, for example the [String]
value of sol_keys
.
The only way to decode this JSON with JSONDecoder
is to implement init(with decoder
, decode the sol_keys
and create your own temporary CodingKeys
to be able to decode the arbitrary dictionary keys.
First declare the custom CodingKey

I have looked through other threads regarding trying to parse JSON data where a JSON array has no name. From what I have found you need to use a unkeyedContainer but I'm not entirely sure from the examples I have seen how this works with the data model.
