Based on CoinGecko API documentation.

• For fetching the top ten cryptocurrencies by market cap, their details, and historical price data, use the /coins/markets endpoint to get the list of top cryptocurrencies sorted by market cap.
• For details on a specific cryptocurrency, use /coins/{id} where {id} is the cryptocurrency ID.
• For historical data, /coins/{id}/market_chart provides historical price data over time.

Here’s a pseudo-implementation sketch:

// Fetch top ten cryptocurrencies by market cap
func fetchTopCryptocurrencies() {
    let url = URL(string: "https://api.coingecko.com/api/v3/coins/markets?vs_currency=eur&order=market_cap_desc&per_page=10&page=1")
}

// Fetch details for a specific cryptocurrency
func fetchCryptoDetails(id: String) {
    let url = URL(string: "https://api.coingecko.com/api/v3/coins/\(id)")
}

// Fetch historical market data for a cryptocurrency
func fetchHistoricalData(id: String, days: Int) {
    let url = URL(string: "https://api.coingecko.com/api/v3/coins/\(id)/market_chart?vs_currency=eur&days=\(days)")
}
